can any body told me, on 05 GS300, which lights can be changed to LED w/o panel warning? I don't want to add resistor or something to remove the warning due to less power consumed by LED. For head, I know low beam is 9006 but not sure which LED brand is good. I think big light are all use 5W led chip, so for 6LED(each side 3) the power is ~30W or 3000~4500 lumin, for 12LED one it doubled. Most LED light are from China, like its li-ion battery the power is listed at will, little has knowledge of light pattern, and more important I don't know which model last.

I changed the third back light above back seat and panel always show warning or burnt symbol. I used to try LED 9006, you can see they are bright but not on road, most has poor focus. Latest 9006 doubled the LED because of this, yet more LED means worse focus right? For those of symmetric shaped at each side of LED, they never consider light pattern required for cars?

Any one has recommend model#? tor list of bulb type for this car? hanks

For tail lights you'll get a warning for signal, running light and brake light. Not familiar with how the headlights work on your car. I find this site useful for headlight bulb recommendations.

The power consumption is irrelevant.
LED bulbs for signaling lamps should have the appropriate resistors to prevent the light-out fault and hyperflashing.
All the interior lamps can be changed to LED without triggering a fault.
Sylvania's automotive bulb tool is still my go-to for finding bulb types in any vehicle.

All my interior bulbs come from Superbrightleds.com Reverse lights are Auxito.

thanks for help, I upload what I edited one not sure 100% correct:

I purchased this from Amazon:

10-Pack 194 LED Bulb, LBRST Error Free T10 LED Bulb, White 6000K Super Bright 168 LED Bulb, 921 2825 W5W LED Replacement Bulb for Dome Map Door Instrument Licenses Plate Light for $8.49

I replaced: (2) lic plate light, (1) luggage/cargo light, (4) 2/rear doors, (2) one for each front door with one left over. All were the 168/194 bulb and were not polarity sensitive.

Next I will replace: (1) 30mm Festoon Dome light, (2) BA9S reading lamps (all part of the central overhead console, (1) 74 Green color for ashtray, (1) 74 white for glove box.

I need to replace the front footwell (1 or 2?), (2) Vanity lights, possibly will tackle unsoldering the leds mounted for the Mark Levision stereo controls. The lights for FM, CD, AM etc are no longer lit.

The License Plate lights in my 2003 Lexus GS 430 were 168/194s, not T4W ... T4W is not listed as one of the bulbs this kit replaces.

I'm also looking to change over my other cars vs doing one at a time i.e., easier/cheaper to buy quantity.

Basically every failed light indicator in your dash will be illuminated once u add a LED to the circuit. I used variable relays to solve the hyper flash in my vehicle. The resistors were all Mickey Mouse, unless u have are extremely talented at incorporating something so unusual into the wire harness. So I bagged that option and removed the bulbs from the dash that indicate a burned out light bulb. I figured that the lifespan of an LED should exceed the lifespan of the rest of the Vehicle and probably it’s owner too.

Not true in my case for interior lights. As I posted, I replaced almost all of my interior lights with LED (9) and no failed light indicator ... 2003 GS430

thanks. it is nt LED problem but I have drive front marking bulb fail, which is very hard to replace - very bad construction

dwoods801

I was trying to be funny, if u install a LED and don’t get a warning light, that just means that there isn’t a warning light for the circuit.

U can simply start with no warning light situation then remove a bulb, check of warning lighy comes on. If yrs then part of the earning light system if not......

I have replaced pretty much every bulb in my 05 GS430 in the interior and exterior and no warning lights. The only ones I have not done so far are the front and rear turn signals and brake lights. Everything else has been done with no issues. Let me know which bulb you are having an issue with and I can let you know which brand I bought. Got all my bulbs on Amazon.
